P0340 and Bank1 Misfire
I've had this code for a while now and ignored it because it wasn't causing any problems until recently, it started going into limp mode at random times. 90% of the time it was at the top of 2nd or 3rd at full throttle, it would hit on its own limiter the SLIP light would come on and it would just feel weak. But there were times when it just popped up while I was cruising.
Then I heard a misfire, though once i turned my car off it stopped. I wasn't sure what it could be but the only code i had to work with was the "P0340 Camshaft Position Sensor A Circuit Bank 1 or Single sensor" So I replaced that and it solved nothing
Now last night it sounds like an entire bank has started misfiring, at this point both sensors had been replaced within the year so I pulled them to check if it or the wiring looked damaged but they seemed fine. (spark plugs were all replaced recently, coils haven't replaced by me but it's unlikely because the entire bank shut down at the same time)
Does anyone have any knowledge on what might be causing this?
